SPECIFICATION forming part of Letters Patent NO. 722,525, dated March 1-07 1903.

Y Application filed July 30, 1902. Serial No. 117,641. (No model.) Y

To a/ZZ whom z'f may concern,.-

Beit known that I, FERDINAND MATHEYER, a citizen of the United States, and a resident of .the city ofY New Yorkborough of Manhattan, in the county and VState vof New York, have invented a new and Improved Intestine- Cleaner, of which the following is a full, clear, and exact description.'

The invention relates to butchering; and.

its object is to provide a new and improved intestine-cleaner which is ,simple and durable in construction, very effective in operation, and arrangedto thoroughly and quickly wash and lengthwise split open the intestines without requiring great skill on the part of the operator.

The invention yconsists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specication, in which similar charactersvof reference indicate corresponding parts in all the views.

Figure lis a side elevation of the improvement. Fig. 2 is a rear ,side elevation of the same, showing the cover of the hood for the gearing in an open position. Fig. 3 is a plan view of the improvement. Fig. 4 is a cross-section of the same on the line 4 4 of Fig. 3. Fig. 5 is a similar view of the same on the line 5 5 of Fig. 3; and Fig. 6 is a sectional plan View of the nozzle-guide, the section being on the line 6 6 of Fig. l.

On the front end of the bed A, on which the machine is mounted, is bolted or otherwise secured a longitudinally-extending nozzleguide B, having a passage B', connected at the rear end with a similar passage A', formed in the bed A and connected with a watersupply pipe C, as plainly shown in Fig. 6. The forward end of the guide B and its passage B' terminate in a knob-like nozzle B2, adapted to pass into the intestine, so that the water from the nozzle washes the intestine as the latter is fed forward over the guide B bya pair of toothed feed-disks D and D', secured on a transversely-extending shaft D2, journaled in suitable bearings on the free end of a swing-frame E, provided at its rear end with trunnions E', mounted to turn in bearings A2, forming part of the bed A. The extreme rear end of the swing-frame E is provided with a counterbalancing-weight E2 to permit the operator to conveniently swing the'frame E upward at its forward end for the purpose hereinafter more fully described.

The top B3 of the nozzle B, below the peripheral faces of the feed-disks D D', is segmental and in close proximity to the teeth of the disks, and the said teeth extend close to the outer faces of longitudiDaily-extending ribs B4, forming part of the nozzle-guide B, so that when the machine is in operationthe said teeth of the feed-disks engage the intestine at two points to feed the same lengthwise forward over the nozzle-guide B and to a slitting-disk F, extending between the rear bottom portions of the disksD and D' and into a longitudinally-extending slot B5, formed in the nozzle-guide B.

The slitting-disk Fis secured on a shaft F', journaled in the forward end of the swingframe E, and vthe said feed-disks D and D' and the slitting-disk F are rotated in unison from the main shaft G, journaled in the trunnions E' of the swing-frame and carrying fast and loose pulleys G and G2, connected by a belt with other machinery for imparting a rotary motion to the shaft G. The pulley-belt referred to is shifted from one pulley to the other by a shifting-fork G2, held on a shaft G4, journaled in suitable bearings carried by the swing-frame E, and-the forward end of the shaft G4 is provided with a handle G5 under the control of the operator standing in front of the machine and guiding the intestines to the nozzlev B2 ofthe guide B.

The gearing for driving the disks D, D', and F from the main shaft G is positive and consists of a sprocket-wheel H, secured on the shaft G and connected by a sprocket-chain H with 'sprocket-wheels H2 and H3, of which the sprocket-wheel H2 is attached to the shaft D2 and the sprocket-wheel H3 is secured on the shaft F'. The sprocket-chain H' also passes over a tightening sprocket-wheel H4, journaled on an arm H5, fulcrumed on the shaft F and secured in place bya clampingbolt H6, held on the swing-frame and engaging a segmental slot H7 in the arm H5, as

IOO

The driving-gear described is inclosed in a hood I, having a hinged cover I', so as to render the gearing dust, dirt, and water proof. The hood I is attached to the swing-frame E, which also carries a hood J, having a hinged cover J,partlyinclosing the disks D,D',and F.

When the machine is running, the operator passes one end of the intestine over the nozzle B2 until the teeth of the feed-disks D D' take hold of the intestine and feed the same along the nozzle-guide B. The teeth of the feed-disks D D' in engaging the intestine stretch the same over the ribs B4, and Ias the peripheral cutting edge of the slitting-disk F extends between the said ribs B4 it is evident that the cutting edge effectively cuts the intestine open at the top.

When itis desired to render the disks D, D', and F inactive without stopping the said disks, then the operator swings the swingframe E upward and locks the same in an uppermost position by a pin or like device inserted in an aperture K in a segmental arm K, projecting upwardly from the bed A and passing through a bearing E3, formed on the swing-frame E. (See full and dotted lines in Fig. l.) When the swing-frame is in this uppermost position, the operator has convenient access to the nozzle-guide B for cleaning or repairing purposes and access to the disk for sharpening the same without stoppin g the machine. When the frame is in the uppermost position, the rotation of the main shaft G, the gearing, and the disks D, D', and F may be stopped, and then the operator has convenient access to the said disks for repairing or other purposes.

It is understood that when the frame E is in its lowermost position its front end rests on the front end of the bed A, so as to hold the disks D, D', and F in proper relation to the nozzle-guide B.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. An intestine-cleaner comprising a pair of revoluble toothed feed-disks, a revoluble slitting disk extending between the feeddisks, a fixed guide for the passage of the intestine, having a slot for the slitting-disk, longitudinal ribs on the walls of the slot and projecting above the upper face of the guide, and a nozzle connected with the water-supply and adapted to pass into the intestine in advance of the said disk,` a main shaft, a gearing for rotating the said disk from the said main shaft, and a swing-frame fulcrumed on the main shaft and carrying the disks and v the gearing, as set forth.

2. An intestine-cleaner provided with a fixed guide having a longitudinal slot, a waterpassage terminating in a nozzle at the free end of the guide, and longitudinal guideribs projecting from the top of the guide, ou opposite sides of the slot, as set forth.

3. An intestine-cleaner comprising a pair of revoluble toothed feed-disks, a revoluble slitting-disk extending between the feeddisks, a fixed guide for the passage of the intestine, having a slot for the slitting-disk, a nozzle connected with a water-supply and adapted to pass into the intestine in advance of the said disk, a main shaft, a gearing for rotating the said disk lfrom the said main shaft, a swing-frame fulcrumed on the main .shaft and carrying the disks and the gearing,

a hood for the gearing, and a hood for the disks, both hoods forming parts of the swingframe and provided with hinged covers, as set forth. p

In .testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FERDINAND MATHEYER.
